Really cool and should be useful for quite some GPU debugging scenarios. Let's get it in. |

This doesn't have them yet for prim, texture, target, etc. type breakpoints but at least for addresses and register changes.
More conditions would be nice - for example on screen-space vertex coords for a prim, and for actions like jump/etc. (currently not possible in UI.) I also think it could be useful to have log-only cases. That said, this is a good start on better GE breakpoints.
I created a little syntax (maybe could be used to "assemble" commands too...) but it's currently esoteric. For example, you could set a breakpoint on blend mode and use the condition:
(data & 0xF0) == (10 << 4) && blendfixb == 0x112233. In the future I kinda want to add fields so you could dodata.dstfactor == 10 && vtype.through == 1or similar. Note it'sdatabecause that's the incoming value (blendmodeis unchanged as yet.)It might be nice to add constants too as "symbols" but that might get even more esoteric (example:
data.dstfactor == GE_DSTBLEND_FIXBordata.dstfactor == data.dstfactor.fixedor something.)GECmdFormatcaptures pretty much all the bit patterns there are, but I might think about changing it based on fields. Not sure.-[Unknown]
